I am having a problem with my Windows 7 Pro edition when burning data to a CD-RW.

When I add new data to existing data already initially burned on the CD-RW, the data has been written correctly to the disk, but when I view the disk after writing the new data, I never see the new data...the only data I see is the data that was written to the CD-RW at the FIRST burning. When I place my CD-RW in my other computer with Windows XP, all the data appears...initial burning and all subsequent burnings; place it in my Windows 7 CD drive and NO secondary data is showing. In one program I have for burning, I actually get a dialog box saying "the data has been written correctly to the disk, but the number of files does not match the expected file count. Most likely, the file system structure has not been written correctly and some files will not appear on the disk." What is going on with this "file system structure has not been written correctly?"

This is a new wrinkle in the sheet for me. I have 5 CD/DVD read/write drives, and they all work the same...only initial files show and other files are not visible when re-burning to a CD-RW. It is really an Agatha Christie mystery to me.

Any help with this frustrating problem would CERTAINLY be appreciated. Thanks in advance.

Create a new drive image before making system changes, in case you need to start over!

No I have not used the Win7 burn to burn these CD-RW...I will give it a try. Sounds like another case of Microsoft wanting to take control again...why can't a third party burn program do the job? I will certainly take your suggestion and see if that works. Thanks for your input; I really appreciate it.

I did not think of having to format the CD-RW before writing to it. I have never had to do that in the past with XP so I just figured all would be the same. Thanks very much for your suggestion. I will give that a try and see what happens. Hope this as well as the other input to my post does the trick.
